I think that when using a shackle reversal on flat springs there is not much gain, but when you add lift springs to SUA set-up they really help smooth out the ride. One other thing that they do is take off some of the tension of the front leafs, mine have started to bend near the spring hanger because when I go up ledges and stuff the force gets pushed right into the spring hanger.

but if you really think of how a shackle reversal works when you hit that ledge your tire will pull away from the ledge because that is the way your shackle allows it to move instead of with the shackle in front it forces the tire up the obstacle as it cycles...but it does put more stree on the springs...you only need a smooth ride for a Pokey Jeep (aka State Street Jeep...hasn't this been discussed before)

I also think shackle reversals are harder on the front part of your frame. No engineering background here but....

With or with out shacles, the pivot point is still the center of your rear axle. W/ normal shackles, most of the force is being absorbed by the fixed point behind the front axle and energy is being released out the front as the spring compresses. However, reversing the shackles adds 4 feet to the radius from your pivot point and putting increased forces toward the front of your frame where the fixed point it now.

So with all that, I still have one. Like I said, easiest way to use the wrangler springs.

Oh and when I'm all done, who's going to inspect it for me so I can still get it registered? LOL

Go coils or CoilOvers. The fact that you asked about registering it means you want it road worthy. 1/4 ellip setups have extreme amounts of body roll unless you keep lift to an absolute minimum. The problem comes in the fact that usually the lower leaf is unrestricted, or the spring is built on a pivot (like that one pictured above)...so when you turn a corner the body will control the spring instead of the spring controlling the body.

Besides, when you do it right ~ its cheaper to go coils.

welcome snoop.

What do the custom 1/4 elips you use run cost wise?

I get mine from Alcan ~ $150 - $250 PER PACK last time...can't remember...

Coils are $100-$175 for the pair....

Cost benifet....and Bling benifet...

I've seen few dudes bend their springs by hitting their front shackles on crap. IMO that makes a reversal worth it.

pros and cons each way,

Shawn didn't you bust a couple of tcases with a SR?
